With the “2009 Monodzukuri Small and Medium Enterprise Product Development Support Subsidy (Prototype Development Support Program),” we have successfully reduced contact resistance by coating SOFC interconnectors and current collector mesh cobalt nickel plating to improve solid oxide fuel cell performance and reduce degradation. The SOFC interconnector and current collector mesh cobalt nickel plating coatings have successfully reduced contact resistance.
This is the realization of high-life and high-performance SOFC coatings.
ASR Test Result
ASR test result of test piece with Co-Ni coating and without coating. Succeed in reducing ASR and developing performance by coating.
ASR Test Result *1,000hour
ASR 1,000hour test result of test piece with Co-Ni coating. After 1,000h ASR remains low and this shows enhanced durability.
Similar to Co-Ni plating, a coating process by spraying MCF powder is available as a method to maintain good electrical conductivity for a long period of time at SOFC operating temperatures and to suppress Cr evaporation from metal interconnectors.
MCF (MnxCoyFe3-x-yO4) powder from H.C. Starck is used for this coating process.
Magnex Co., Ltd. also accepts orders for coating treatment of MCF.
The photo on the left is an SEM photograph of a thermal spray deposition using H.C. Starck's MCF powder (Amperit 865®/particle size: 45-15μm) under standard thermal spraying conditions.
